If you havent been to your local Unos recently, youre in for a great surprise. Sure, its famous deep-dish (read high-fat) pizzas still hold court, but nutrition has become the word of the day with a completely trans fat–free menu and plenty of grilled entrees (including antibiotic-free chicken). Adding to the healthy variety: whole-grain pasta and brown rice, organic coffee and tea, and flatbread pizzas that have half the calories of deep-dish ones. Plus, you can add a salad to your pizza for half-price because, according to the menu, “We want you to get some greens in your diet.” Now thats a blue-ribbon commitment to health. Another reason Unos is at the top of our list: You know what youre eating. In the lobbies of most of the restaurants locations, there are Nutrition Information Centers that detail ingredients, fat and sodium contents, and calories and fiber of every item, in addition to gluten-free options.

Danger zone: Deep-dish pizzas can pile on the fat.

We love: The Penne Bolognesejust 16 grams of fat (well within the daily recommended max of 65 grams of fat for a 2,000-calorie-a-day diet).

Can a buffet-style restaurantthat symbol of American overindulgencepossibly be one of the healthiest restaurants in the country? It can in this case, because this salad-soup-and-bakery eatery (Southern California locations are named Souplantation, everywhere else theyre called Sweet Tomatoes) uses produce so fresh that its guaranteed to have been “in the ground” 24 hours before its in a refrigerated truck on its way to the restaurant. At the salad bar youll find seasonal vegetables like squash and bell peppers, freshly tossed and prepared salads, and a great range of nonfat dressings. San Marino Spinach With Pumpkin Seeds and Cranberries, anyone? This is paradise for vegetarians, vegans, and anyone whos looking for a low-sodium, low-fat, high-nutrient meal outside the home.

Danger zone: Plate overloadafter all, its all-you-can-eat.

We love: The Tomato Spinach Whole Wheat pasta, a delicious combo of whole grains and veggies.

This cozy cafe-style restaurant transforms normally less-than-healthy foods into betterand still tastyoptions: a half-pound cheeseburger wrapped in lettuce (thats right, no bun); the cutely named Naked French Market Onion Soup, served without cheese. Another thing to love is the way that Mimis clearly steers you toward its healthy options. Its “Lifestyle Menu” points you to low-carb picks like the fish of the day served with fresh steamed veggies. Also, Mimis keeps portions small, so you can get away with occasionally having one of their more indulgent entrees like the Sweet & Sour Coconut Shrimp (608 calories).

Take the best aspects of Asian cuisinea combination of fresh vegetables and proteinsurround them with healthy influences such as whole-grain brown rice, wild-caught, sustainable Alaskan salmon, and all-natural chicken, and you have a recipe for delicious, healthy dining. Wok-based cooking (which requires less oil) using soybean oil keeps fat contents low, and less sodium in the sauces rounds out P.F. Changs healthy take on Chinese food.

Special credit goes to their nutritional information being based on the whole entree, not a single serving like at most places.

Danger zone: Traditional, fat-dense items such as Lo Mein Beef.

We love: Carb-free vegetarian lettuce wrapswok-seared tofu, red onions, and water chestnuts with mint and lime, set in lettuce cups.

You wouldnt think a restaurant that prides itself on sausage could muscle its way into the top five healthiest restaurants in the country. But Bob Evans scores high on its dinner menu, which has plenty of low-carb, low-fat entrees and alternatives for children and adults (chicken tenders that are grilled instead of fried, potato-crusted flounder, and salmon stir-fry). Look for sides like steamed broccoli florets and fresh fruit, and enjoy old-fashioned family meals in a modern, nutrition-forward way.

Danger zone: Breakfast, where bacon and sausage are kings.

We love: Healthy options on the kids menu, like slow-roasted turkey with mashed potatoes and glazed baby carrots, and fruit and yogurt dippers for dessert.

If wed done this survey in 2004, Ruby Tuesday might have won the blue ribbon for printing all its nutritional content right on the menu. It was revolutionary, and, frankly, it didnt last. But the healthy ethos survived in the chains ingredients: organic greens, hormone-free chicken, trans fat–free frying oil, and better-for-you beverages including Jones organic teas and made-to-order drinks like all natural lemonades (think real fruit and juice). Its easy to find the good stuffits highlightedand the offerings range from a chicken wrap in a whole-wheat tortilla to broiled tilapia.

Danger zone: Comfort-food entrees like Gourmet Chicken Potpie, which piles more than half your daily calories on the plate.

We love: That theyve even healthied-up the burgers, offering veggie and turkey versions.

This Italian eatery puts its entire menus nutritional content online, so you know before you go what to steer clear ofmainly, the massive baked pastas. But what pushed Macaroni Grill onto our best list is its “Sensible Fare” menu, with entrees like Simple Salmon, a grilled fillet sided by grilled asparagus and broccoli. Grazie for whole-wheat penne available as a substitute in any dish. And bravo for including a grilled skinless chicken breast with steamed broccoli and pasta on the kids menu.

Chevys makes a big deal out of the “fresh” in its name, and with good reasonno cans in the restaurant, fresh salsa blended every hour, fresh avocados smashed every day for guacamole, and watch-them-made tortillas. All oils are trans fat–free, and the Mexican-style fare has lots of healthy options including Grilled Fish Tacos.

Danger zone: Sodium counts. To get below 1,000 milligrams, youll need to get those Chicken Fajitas with no tortillas, tomalito, rice, sour cream, or guacamole.

We love: Fresh fish of the day, grilled and served on a skillet with homemade salsa.

Like Macaroni Grill, this Italian eatery has great-for-you options, as long as you keep your wits about you (again, avoid the baked pastas!). Use the olive-branch icon on the menu to find low-fat “Garden Fare” items such as Venetian Apricot Chicken, (448 calories, 11 grams fat). Even the fries arent a disaster, because theyre done in trans fat–free oil. You can grab some whole-grain goodness, too, by choosing the whole-wheat linguine at dinner as a substitute for any pasta.

Yes, the home of the Lumberjack Slam and Moons Over My Hammy offers lots of skinny options to counter its fatty mainstays. “Fit-Fare” dishes such as the grilled-chicken-breast salad, and tilapia with rice and veggies, each have less than 15 grams of fat. Dennys also posts full nutritional information on its Web site. Its use of trans fats to cook its French fries kept it from landing higher on our list, but the rest of the fried food is trans fat–free.

Danger zone: Breakfast specials, especially the Meat Lovers Scramble, which is as bad for you as it sounds.
